Plumb bob system for the building materials industry
It is not that easy to determine the fill level of a closed silo. Nevertheless, in many fields it is necessary to know the quantity of the material stored – as, e.g., cement for the production of building materials. Only if the actual stock is known, supplies may be ordered early enough thus avoiding any shortage in supply or production bottlenecks.
Level measurement – simple and accurate
The measuring instrument basically consists of an electromechanically driven reel, a rope and/or a tape and a sensing weight fixed at the end. The instruments are mounted on the roof of the silo. When lowering the sensing weight into the container, the tape and/or the rope are wound off the reel until the sensing weight rests on the material to be monitored. The rope tension indicates if the sensing weight is already in contact with the bulk material. When winding up again, the revolutions are counted as well. In this way, the measured value is verified...
